IMPROVEMENT IN CHAMBER-CASES.

Specification forming part of Letters Patent No. 154,140, dated August18,1874; application filed July 27,1874.

l chamber-cases; and it consists in a case or frame to receivethechamber, and which is provided with a spring-bottom for pressing thechamber up against the top of the frame.

It also consists in the arrangement and combination of devices whichwil] be more fully described hereafter. y

The accompanying drawings represent my invention.

a represents a frame or case,`of any suitable shape, just large enoughto receive the chamber, and which is raised up above the iloor by thelegs b. Through the top, just above the chamber, is made the holec,which is covered by the hinged cover d. The top and bottom parts of ltheframe are made of Wood, and clamped together by the bolts e, while theside is made of sheet metal, and through which side is formed a door forthe removal and insertion of the chamber. In the frame is placed themovable bottom'g, upon which theA chamber rests, and under which is acoiled or otller spring, h, which holds the vessel up against the underside ot' the top of the frame. Around the hole c, on

the under side of the top, is placed a small rubber tube, i, which formsan airtight joint around the top of the vessel, and prevents anyunpleasant odors from escaping into the frame and thenceinto the room.Attached 4 to the movable bottom g, by means of a connecti-ng-rod, j, isa lever, l, which is pivoted at one end to one ofthe legs b, extendsacross under the frame, and has a treadle or handle `formed upon itsother end, by which the lever is operated. By bearing down upon this1ever the vessel can be lowered so as to be no longer pressed upwardagainst the top of the frame, when it can be readily removed or'inserted. Adjustably attached to theunder side of the cover by means ofbolts l and springs 2 is a perforated cup or vessel, o, in which adisinfectant is placed, and every time the lid is closeda portion of'the disinfectantis sprinkled in the vessel. The wooden rim, by means ofwhich the cup is secured to the lid, is sufficiently thick to extenddown through the hole c, and has a tube of rubber, 5, secured to itsedge, which bears down upon the flange of the vessel and forms anair-tight joint for preventing' the odors from escaping into the room.By means of the springs 2 the rim is made adjustable, so as to litchambers of dif ferent heights. Extending out from the side of the legb, nearest to the treadle end of the lever, is a small catch, whichholds the lever down, when so desired.

Instead of the lever here shown a screw may be used for the samepurpose.

Having thus described my invention, I claim- 1. The combination of thecover d, provided with the adjustable spring-disk and packing 5, withthe bottom g and spring h, substan tially as set forth.

2. The lid d, adjustable spring-rim, provided with a packing, 5, andperforated cup o, the parts being combined as and for the purposedescribed.

In testimony that I claim the foregoing I have hereunto set my hand andseal this 17th day of July, 1874.

WILLIAM HINMAN.
